Your PitcherPro needs a fresh cartridge every three months to keep doing what it does best. These are the genuine Tappwater replacement refills — the same advanced microfiltration technology as the original, made from organic activated coconut shell carbon. Swapping one out takes seconds: remove the lid, unscrew the old cartridge, screw in the new one, give it a 60-second rinse under the tap, and you're back to clean water. No tools, no fuss. Pick up a twin pack and you've got six months covered in one go. What the filter removes Each refill cartridge tackles 80+ contaminants including: Chlorine, bad taste & odour Limescale (reduced by up to 80%) Microplastics Heavy metals including lead and mercury Pesticides & herbicides PFAS & PFOS Nitrates Sediment, rust & scale Bacteria including salmonella and legionella (>1–2 microns) Essential minerals — calcium, magnesium, potassium — are retained, and alkaline balls naturally raise the pH for a smoother, fresher taste.
